CABLE-RETAINING SHROUD.

, Application filed June 22, 1925. Serial No. 38,715.

My invention relates to electric switches and particularly to switches of the fluid break type having tanks which are adapted to be raised and lowered by means of a cable wound upon a drum. With such apparatus.

and when a steel cable has been used, dilfl culty has been experienced with the cable getting out of place on the drum when allowed to slack. It is an object of my invention to provide a simple and efliective means which may be carried by the winding drum claims.

Referring to the drawing, Fig. 1 is a side elevation of a portion of an oil switch together with an attachment including my in vention; Figs. 2 and 3 are end and side views respectively of the cable winding drum and shroud involving my invention and Fig. 4 is a fragmentary cross sectional view of the drum and shroud.

In Fig. 1 of the drawing I have shown my invention applied to a tank raising and lowering attachment for an oil switch. The switch is of well known construction, a part only of which is illustrated including por-.

tions of the frame 1 and the tank 2. The tank raising and lowering attachment 3 is adapted to be brought up to the switch against which the arm 4 may bear to brace the attachment. The attachment has a drum 5 around which is wound the steel cable 6 which passes up over the pulley 7 at the top and thence to the switch where it is shown passing over the pulley 8 to pulley 9 of the tank attaching block 10, to pulley 11 and back to the block 10. The drum 5 is shown adapted to be rotated by a hand crank 12 through worm gearing 18.

\Vhen the cable is allowed to slack as for example after the tank has been lowered to metal, each end of the strip having laterally extending ears 16 through which pass the cable passes.

bolts 17 thus forming an eye through which the cable passes. 'Thebody portion of the shroud is shownof such a width that it covers the cable when the same is wound up on the drum and it is retained laterally on the drum by the side flanges 18 thereof. As the drum is rotated to wind or unwind. the cable the shroudxrides loosely on the drum, the ends of the shroud being drawn together by bolts 17 only sufficiently to prevent the turns of the cable from springing out' of place when the cable is allowed to slack;

While I havedescribed only one'embodt ment of my invention, I do not wish to be limited to the particular form shown and described as it will be apparent that modifications therein may be'made without departing from the scope of my invention, as set forth in the appended claims.

\Vhat I claim as, new and desire to secure 1 by Letters Patent of the United States, is, 1. In a device of, the class described, a winding drum having side flanges, a cable secured at one end thereto and wound therewinding drum, 'a metallic cable secured at one end thereto and wound thereon and means for preventing the displacement of the cable when slacked comprising a shroud loosely wrapped about the drum carrying the cable and having its ends connected together forming an eye through which the 3. In an electric switch, a steel cable, a drum, upon which the cable is'adapted to be wound and'unwound having side flanges, a

sheet metal shroud having its end portions extending substantially parallel and its in tel-mediate portionembracing the drum and cable thereon between the flanges, and means connecting the end portions of the shroud for adjusting the same on the drum.
